NlTE JACOB MANDREY, OF NEW YORK, N. Y.

SNOW-MELTER.

SPECIFICATION forming part of Letters Patent No. 662,280, dated November Application filed January 18, 1900. nerial No. 1,898. (No model.)

To all whom it rmty concern:

Be it known that I, JACOB MANDREY, a citizen of the United States, and a resident of the city of New York, borough of Bronx, in the county and State of New York, have invented a new and Improved Snow-Melter, of which the following is a full, clear, and exact description.

This invention relates to improvements in machines for melting snow; and the object is to provide a machine by means of which snow may be quickly and economically removed from a street, the snow being dissipated in the form of steam, thus obviating the necessity of carting the snow away to dumps or scows, as is the usualpractice, thus effecting a great saving of cost in snow removal.

I will describe a snow-melter embodying my invention and then point out the novel features in the appended claims. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a snow-melter embodying my invention. Fig. 2 is a partial section on the line 2 2 of Fig. 1. Fig. 3 is a partial section on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal section of the device, and Fig. 5 is a rear elevation.

Referring to the drawings, 1 designates the side rails of the machine-frame mounted at its front end on a truck 2, while the rear ends of said side pieces are connected to the axle 3 of the rear wheels 4. A furnace or heater 5 is mounted to swing between the said side rails of the frame. As here shown, the rear portion of the heater has pivotal connections 6 with the axle 3 or with the side bars of the frame at the rear end.

Arranged within the heater is a grate 7, be-

low which is an ash-pit 8, and the heater is provided at its rear end with a door 9. The forward portion 10 of the heater is inclined downward and terminatesin a shoe or scraper 11, adapted to scrape up the snow as the machine is drawn along. The shoe or scraper portion may be raised upward when desired to prevent it from engaging with the ground by means of a lever 12, adjacent to the drivers seat 13 and having a link connection 14 with a crank-arm 15 on a shaft 16, and also on this shaft 16 is an arm 17, from which a chain 18 extends to a connection with the forward end of the furnace. Smoke-stacks 1-9 com municate with the interior of the furnace at. the forward end, there being one smoke-stack at each side, and a forced draft is provided by means of blowers arranged in casings 20, supported on the furnace and having pipes 21 leading to the ash-pit. The blowers are operated by sprocket-chains 22 passing around sprocket-wheels 23 on a shaft 24:, supported in standards 25 on the rear end of the furnace and also around pinious 26 on the fanshafts.

Rotary motion is imparted to the shaft 24: by means of sprocket-chains 27 at each side of the machine, said sprocket-chains passing around sprocketwheels 28 on said shaft 24 and around sprocket-wheels 29, attached to the hubs of the rear wheels 4.

Mounted on a shaft 30, having bearingsin standards 31 on the forward end of the furnace, are sprocketwheels 32, with which sprocket-chains 33 engage, these chains also passing around sprocket-wheels 34 on the shaft 24:. Connected to the opposite chains 33 and extended across the upper surface of the heater or furnace are conveying-scrapers 35, designed to carry the snow up the incline 10 and also onto the horizontal top portion of the furnace or heater.

A coal bin or holder 36 is mounted on legs 37, attached to the frame 1, and from this coal bin or holder a chute 38 leads rearward and is inclined down ward, so that coal will pass from the holder 36 through said chute in order that a person standing on a platform 39 may receive the coal from the chute to place it in the furnace.

In operation as the machine moves forward and the shoe end of the heater is in its lowermost position the snow will be scraped up and then caught by the scrapers and carried along the top surface of the heater or furnace. This top surface will be sufficiently heated to melt the snow and convert the same into steam, which upon condensation may pass off through sewers or the like.

As before mentioned, when it is not desired to scrape up any snow or when the machine is passing over a surface not covered by snow the forward end of theheater may be elevated by means of the lever 12.

This machine at the most will require but two attendants, one as a driver and the other to feed the furnace. It is obvious, however, that one man canboth act as a driver and a feeder for the furnace; but this of course will require his dismounting from the drivers seat and stopping the machine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.-

1. A snow-melting machine, comprising a frame, a truck to which the forward endof the frame is connected, rear wheels supporting the rear end of the frame, a heater having swinging connection at its rear end with the frame, the said heater having a downwardly-inclined front portion terminating in a scraper, a blower for the furnace, and a smoke-stack at the forward end of the furnace, substantially as specified.

2. A snow-melter, comprising a frame I mounted on wheels, a furnace mounted to swing in said frame, said furnace having a I downwardly-inclined forward portion,s mokepipes attached to opposite sides of the furabe, at: h o wa nd. and adapted to ceive products of combustion from the indriven from the rear wheels of the machine, 7

and scrapers extended across the furnace and connected to said chains, substantially as specified.

In testimony whereof I' have signed my name to this specification in the presence of two subscribing witnesses.
